Abstract:
The present invention relates to an electrochemical cell characterised in that it comprises at least a positive electrode which comprises manganese oxide physically separated from at least a negative electrode which comprises an aluminium alloy, and wherein said positive and negative electrodes are electrically connected through a neutral pH electrolyte. Further, the present invention relates to the use of the electrochemical cell, preferably as a button battery in hearing aids.
Abstract:
Eine Vorrichtung zur Entfernung von Schadgasen aus der Atmosphäre besteht aus einer in der Erdatmosphäre autonom operierenden Plattform, deren Gehäuse in Leichtbauweise konstruiert und mit Einlässen für die umgebende Atmosphäre sowie mit Auslässen für die aufbereiteten Produkte ausgestattet ist. Im Inneren des Gehäuses sind Einheiten zur Gasextrahierung und -separation sowie zur Speicherung und Aufbereitung von flüssigen und gasförmigen Produkten angeordnet. Die Energie zum Betrieb der einzelnen Einheiten dieses geschlossenen kryogenen Kreislaufsystems wird dabei von Solarzellen erzeugt.
Abstract:
An airship (20) has a generally spherical shape and has an internal envelope (24) for containing a lifting gas such as Helium or Hydrogen. The airship has a propulsion and control system (36, 38) that permits it to be flown to a desired loitering location, and to be maintained in that location for a period of time. In one embodiment the airship may achieve neutral buoyancy when the internal envelope is as little as 7 % full of lifting gas, and may have a service ceiling of about 60,000 ft. The airship has an equipment module (180) that can include either communications equipment, or monitoring equipment, or both. The airship can be remotely controlled from a ground station. The airship has a solar cell array and electric motors (44, 46) of the propulsion and control system are driven by power obtained from the array. The airship also has an auxiliary power unit (52) that can be used to drive the electric motors. The airship can have a pusher propeller that assists in driving the airship and also moves the point of flow separation of the spherical airship further aft. In one embodiment the airship can be refuelled at altitude to permit extended loitering.

Abstract:
The invention relates to a drone comprising: two contra-rotating annular propellers (2, 4) defining a plane therebetween which is referred to as an equatorial plane and is assumed to be horizontal, means for driving the propellers, a load arranged below the equatorial plane, and means (20) for moving the load relative to the equatorial plane, an enclosure referred to as an upper enclosure (6) filled with a gas or a gaseous mixture having a density of less than 1 and arranged essentially above the equatorial plane, and an enclosure referred to as a lower enclosure (8) filled with a gas or a gaseous mixture having a density of less than 1 and arranged essentially below the equatorial plane, the load being placed inside the lower enclosure (8).
Abstract:
The invention relates to an airship (1) comprising a flexible envelope (2) having at least one adjustment region (4) provided with two longitudinal adjustment elements (5, 6) mounted in opposition and mobile in relation to each other between a maximum distancing position and a minimum distancing position, the two longitudinal adjustment elements (5, 6) being connected to each other by a group comprising a plurality of cables (7, 7', 8, 8', 9, 9') crossing the inner space (3) of the envelope, each of the cables (7, 7', 8, 8', 9, 9') cooperating with a plurality of tightening points (10) provided along each longitudinal element. The cables are connected to at least one tightening module (20) that can exert a tightening or loosening action on the cables and thereby bring the longitudinal adjustment elements (20) closer together or move them further away.
Abstract:
A flight vehicle includes a drone (28) with a pair of shaped protrusions (22, 24) mechanically coupled to the drone. One of the shapes is a hollow lift-producing shape (22), such as being a balloon filed with a lighter-than-air gas, and the other (24) of the shapes is below the drone. The shape below the drone may be a hollow shape that does not produce lift, for example being a balloon filled with air. The shapes (22, 24) may be similar in size and shape, so as to provide similar drag characteristics. The shapes may be opposite ends of a support (26), such as a stick, rod, or other (relatively) slender structure. The vehicle includes a payload (12), such as radar calibration equipment or an antenna. The drone may be used to counteract wind forces on the flight vehicle, and/or to otherwise position the flight vehicle.
Abstract:
The disclosed embodiments include a trailer for an autonomous vehicle controlled by a command and control interface. The trailer includes a trailer body configured to retain the autonomous vehicle in an undeployed configuration. The trailer also anchors the autonomous vehicle in a deployed configuration. A tether is provided having a first end coupled to the trailer body and a second end that is configured to couple to the autonomous vehicle. A winch is utilized to adjust a length of the tether to move the autonomous vehicle between the undeployed configuration and deployed configuration. Further, a communication system communicates with the command and control interface and the autonomous vehicle to control movement of the autonomous vehicle between the undeployed configuration and deployed configuration.
